How do you equally divide a row in 5 columns in Bootstrap 4 where it has 12 columns total? Anyone knows?
Bootstrap 4 doesn't use floats like version 3 did so it can automatically space out your columns using just the col class. So for 5 equally spaced columns, just do this:
.col1 {
background-color: red;
}
.col2 {
background-color: green;
}
.col3 {
background-color: blue;
}
.col4 {
background-color: orange;
}
.col5 {
background-color: brown;
